Plant Tours

LA Sanitation (LASAN) is pleased to provide free tours of our water reclamation facilities. On the tours, you will learn what happens to everything that goes down the drain in homes and businesses.

Sewage contains mostly water and solids. As you go through the tour, notice that many of the treatment processes at the plants are designed to separate solids from water. This must take place so that when the wastewater is completely treated it is clean enough to be pumped into a body of water or recycled for other uses.

The solids have value too - they are sent back into the sewer system and flow to the Hyperion Water Reclamation Plant (HWRP) where they are processed into energy resources, soil amendments and fertilizer.

Due to security constraints, tours are available by appointment only. To schedule a tour, please call the number for the corresponding plant. Hyperion Water Reclamation Plant (HWRP) - 310-648-5363
